I am working on coating of different alloys on metallic wire in vacuum condition. I want rapid cooling of coating with the help of helium /argon gas or electrical driven cooling device . Is anyone of you know about electrical device or any suggestion which can do rapid cooling of the coated wire after passing through molten alloy? I used Helium/ argon gas for cooling purpose but i did not complete amorphous nature of coating.
I am not the expert in your field but heard that to receive amprphous metals the people used some cooling rotating device. So may be go to the literature how to obtain amorphous metals-may be you can find there a solution good for you.

If your alloys to be coated are metallic alloys and you want to make them amorphous then you have to use splat cooling technique which is used to prepare metallic glasses. You can go through the literature on metallic glass preparation
Dear all;
please make a simple search on "quenching techniques", than you will find the appropriate one to your situation. Please let me know if this does'nt work. Regards
Quenching is the key word! Construct a simple double walled elongated cylinder and fill it with liq. nitrogen. Let the wire be drawn through the inner opening of the cylinder. Hope it helps :)
